A mechanism for ejecting an electronic card inserted into a card connector is driven by applying an electrical current to a memory alloy wire to cause the wire to retract and the mechanism to move from a first position to a second position. Immediately after the mechanism reaches the second position, another card can be inserted into the connector without waiting for the wire to resume its original length.
